[PERK] Poison Immunity

This perk reduces the amount of damage done to your character per turn from poison.

5 levels
-1 point of poison damage per round per level, and +1 healing per action spent sweating it out of your system

Note - If you have this at level 2, and you get hit by three fire ants (each with level 1 poison) you should take 1 point of poison damage per round.
If you have this perk at level 3, and you're hit by a Giant Scorpion (Level 10 poison), you will take7 points of poison damage per round.  Assuming you survive the fight, you will be able to purge 4 points of poison from your system for each action spent resting.

I think I've experienced this deja vu before...
